When asked, "What are the technological content and barriers of the company's rolled copper foil? Who are the domestic and international competitors? Which companies are downstream clients?" North Copper responded on the investor interaction platform on June 25: The technological content and barriers of the company's rolled copper foil are reflected in: 1. The long process flow of rolled copper foil, involving disciplines such as smelting, rolling, metal heat treatment, and electrochemistry, requires continuous trial production to accumulate a process database. This represents a long-term experiential barrier that cannot be quickly reverse-engineered. 2. Capital and hardware thresholds, with extremely high equipment investment, high barriers for equipment installation, commissioning, and operation, and severe limitations on product width and ultra-thin gauge. 3. Barriers in rolling and forming processes, which are also the highest thresholds—covering product thickness, sheet flatness, internal structure, and mechanical properties, as well as the synergistic barriers of dozens of interconnected processing steps. The consistency control across the entire process is far more demanding than the single-step electrodeposition process for copper cathode foil. Regarding the statement, "The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² copper clad laminate (CCL) project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation," North Copper responded on the investor interaction platform on June 25: The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² CCL project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation. North Copper responded on the investor interaction platform on June 25: The company seizes market opportunities, closely monitors downstream market demand, focuses on R&D for mid-to-high-end copper strip products and structural adjustments for rolled copper foil products, and is committed to filling gaps in its process lines and reaching its capacity standard, striving to turn losses into profits as soon as possible. Regarding the question, "When will the company's semi-annual report performance forecast announcement be released?", North Copper responded on the investor interaction platform on June 25: The company has scheduled the disclosure of its 2026 semi-annual report for August 27. If the conditions for a performance forecast are met, the company will release the announcement within the stipulated time. When asked, "After the implementation of the 'Regulations on the Implementation of the Mineral Resources Law of the People's Republic of China', has the related work on applying for the mining permit for the newly added copper ore at the Tongkuangyu Mine been accelerated? Could you discuss the company's near-term plans? If progress goes smoothly, based on the ore's copper grade and after deducting relevant costs, how much profit is this expected to bring to the company?" North Copper responded on the investor interaction platform on June 24: The detailed survey of deep-seated replacement resources at the Tongkuangyu Mine is a project to add reserves outside the current mining right's boundary at depth (elevation range: 80m to -325m), which is conducive to increasing the company's copper resource reserves and extending the mine's service life. Given that the replacement resources identified by the detailed survey have reached a large scale, according to reserve review and filing requirements, the exploration level must be achieved for resource reserve filing and for initiating the transition from exploration to mining. As the mine's production level shifts downward, the company will conduct further exploration work for deep-seated replacement resources at the next production level. The company currently has no relevant deep exploration plans. Regarding the question, "As a third-generation core substrate material for IC lead frames, could you briefly introduce the production and latest order status of your company's 5,000 mt chromium zirconium copper alloy product?", North Copper responded on the investor interaction platform on June 23: Our company has completed the casting ingot product for C18150 (chromium zirconium copper alloy); the subsequent copper strip process is currently under trial production. There are no orders at present. On June 17, North Copper stated on the interaction platform in response to an investor's question that the company has not yet established a cooperative relationship with NVIDIA. On June 17, North Copper stated on the interaction platform in response to an investor's question that the company has a comprehensive market cap management system, consistently centering market cap management on enhancing intrinsic value. Through methods such as focusing on core business growth, optimizing governance structures, strengthening information disclosure, and implementing shareholder return plans, it is committed to achieving long-term alignment between the company's value and its market performance. Should there be arrangements such as share buybacks or capital increase plans, the company will promptly issue relevant announcements. On June 15, North Copper stated on the interaction platform in response to an investor's question that, relying on scientific research breakthroughs at the Shanxi Provincial Key Laboratory of New Copper-based Materials, the company's copper strip and foil product structure is undergoing further adjustment and optimization. All production and operation activities are proceeding in an orderly manner, and product orders are growing steadily. On June 4, North Copper stated on the interaction platform in response to an investor's question that the company's management places high importance on extending the industry chain and has made positive progress in deep copper processing. During the 15th Five-Year Plan period, the company will rely on its existing copper strip and foil production lines to achieve new breakthroughs in scientific research, product structure adjustment, and capacity enhancement, thereby empowering the company's high-quality development.

The company's 'Zhongtiaoshan' brand Grade A copper is registered on the Shanghai Futures Exchange and the Shanghai International Energy Exchange, and its 'Zhongtiaoshan' brand gold and silver ingots are registered on the Shanghai Futures Exchange. The mineral exploration situation disclosed in North Copper's 2025 annual report showed that the company completed the detailed survey project of deep-seated replacement resources at the Tongkuangyu Copper Mine (below 80m elevation), with primary completed workloads: prospecting roadway 140.6m, 12 drill chambers/2,823.6m³, 12 drill holes (including 3 hydrogeological holes), drilling footage 7,268.62m, 1:2000 special hydrogeological, engineering geological, and environmental geological survey 6㎢, geophysical logging 2,065.61m, and pumping tests for 3 holes; 8,091 samples analyzed and tested, 46 rock/mineral test groups, 99 small-weight samples, 20 copper phase analysis samples, 10 complete chemical analysis samples, and 12 complete water quality analysis samples. On February 20, 2025, the Shanxi Mining Association organized the completion of supervision and field acceptance work for the resource detailed survey project, issuing supervision and field acceptance reports. In early March, the company completed the compilation of the 'Special Hydrogeological, Engineering Geological and Environmental Geological Detailed Survey Report for the Deep Part of the Tongkuangyu Mine'. On March 17, the Shanxi Mining Association organized an expert review which was passed. In May, the company completed the compilation of the 'Detailed Survey Report on Deep-seated Replacement Resources at the Tongkuangyu Copper Mine in Yuanqu County, Shanxi Province' (hereinafter referred to as the report). On May 23, the Shanxi Mining Association organized an expert review which was passed, and an review opinion was issued. According to the report, as of December 31, 2024, within the 80m to -325m elevation range of the Tongkuangyu mining area, cumulative identified industrial orebody (No. 5) resources amounted to 103.718 million mt of copper ore with an average grade of 0.84% and a metal content of 869,600 mt. Associated gold metal content was 8,930 kg at an avg. grade of 0.09g/t; associated molybdenum metal content was 3,727 mt at an avg. grade of 0.011%. Low-grade copper ore resources amounted to 34.625 million mt with an avg. grade of 0.25% and a metal content of 88,200 mt. The scale of discovered resources reached large-size, marking a significant prospecting achievement and providing a solid resource guarantee for the company's industry chain layout. Regarding the company's copper ore resource reserves, North Copper announced in its annual report, As of year-end 2025, the Tongkuangyu Mine had retained copper ore resources above 80m elevation of 204.664 million mt, with a copper metal content of 1.2501 million mt. Additionally, below 80m elevation at the base of the Tongkuangyu Mine's current mining right, the cumulative identified industrial orebody (No. 5) copper ore resources was 103.718 million mt, with an average grade of 0.84% and a metal content of 869,600 mt. For the 2026 production and operation plan, North Copper mentioned in its 2025 annual report: Main product production: copper cathode 300,000 mt, sulphuric acid 800,000 mt, gold ingots 6 mt, silver ingots 60 mt, to maximize economic benefits. A research report from Huaxi Securities on June 14 pointed out: In the medium and long term, copper, as a key metal for energy transition, possesses strategic allocation value under the policy guidance of the 15th Five-Year Plan. On the supply side, entering 2026, major mines globally have continued to experience strikes and production halts this year, keeping the supply profile relatively tight. From a macro perspective, the probability of a US Fed interest rate cut during the year still exists. In the long term, the macro environment supports copper prices, and the US dollar is expected to continue depreciating, supporting a positive outlook on copper prices. Furthermore, strong supply-demand fundamentals support copper prices. China's macro policies are expected to continue exerting force, and stimulus measures in sectors like electric power infrastructure, NEVs, and home appliance consumption could further expand.

[SMM Analysis: Impact on Solid-state Batteries of the Ministry of Commerce Adding 10 US Entities to the Export Control List] On June 22, 2026, the Ministry of Commerce issued an announcement and, effective immediately, formally implemented the "Export Control List (June 22, 2026)," which includes 10 US entities. This export control measure has almost no direct impact on China's solid-state battery industry, but attention should be paid to the indirect link of the rare earth supply chain. (1) China already has export controls on high-end batteries with an energy density exceeding 300 Wh/kg (including semi-solid and all-solid-state), and this measure targeting specific entities is an extension of the existing control framework rather than a new restriction specifically aimed at the solid-state battery industry. (2) The solid-state battery industry is still in the development stage and has not yet generated a significant export demand.

SMM, June 18: The Regulations for the Implementation of the Mineral Resources Law of the People's Republic of China, which took effect on June 15, listed 36 types of minerals, including rare earths, tungsten, lithium, cobalt, gallium, and germanium, as national-level strategic minerals, subjecting them to full-chain, high-intensity control. The prices of Pr-Nd oxide, dysprosium oxide, and terbium oxide saw their third consecutive daily increase on June 17; Orient Zirconium issued a price adjustment notice, raising the prices of its related zirconium products effective June 18, 2026; and the favor of some market funds all contributed to the opening strength of the minor metal sector. As of around 9:57 on June 18, the minor metal industry sector rose by 3.09%. In terms of individual stocks: Orient Zirconium, Shenghe Resources, and Zhongxi Nonferrous hit the daily limit; China Rare Earth, Jintian Titanium, China Northern Rare Earth, China Tungsten High-Tech, Tin Industry Co., and Yunnan Germanium led the gains. Market News Orient Zirconium raised the prices of its related zirconium products effective June 18, 2026 On June 18, Orient Zirconium issued a product price adjustment notice. The notice indicated that based on current market conditions, Orient Zirconium decided to raise the prices of its related zirconium products starting from June 18, 2026, with the price adjustments as follows: zirconium oxychloride products (including mother liquor materials) increased by 1,500 yuan/mt; zirconium dioxide products increased by 4,500 yuan/mt; fused zirconium products increased by 2,000 yuan/mt; at the same time, the prices of other zirconium series products from Orient Zirconium will be adjusted accordingly. [Aidite: The company has already laid out a powder substitute plan and fully implemented it; the new material can replace the original imported powder] On June 17, Aidite stated on an interactive platform while answering investor questions that the company had received a notice from Japan's Tosoh regarding the suspension of zirconia powder supply. To ensure the stability of its own supply, the company had already laid out a powder substitute plan and fully implemented it; the new material can replace the original imported powder, and the entire new product line has passed rigorous customer verification. Currently, several core major clients have completed the switch and signed long-term orders at the recent dealer conference. The company will actively take a series of measures to avoid any adverse impact from the Japanese powder supply disruption. In the future, the company will seize the window of opportunity for high-quality material breakthroughs and, leveraging its technical and delivery advantages, continue to expand its market share. Spot Market Zirconium According to the SMM price assessment, on June 18, the price of zirconium oxychloride (Zr(Hf)O2≥36%) was quoted at 17,500-18,000 yuan/mt, with an average of 17,750 yuan/mt, up 5.97% from the previous trading day. The zirconium industry chain had long been under pressure, with sluggish traditional demand from ceramics and high industry inventories. Zircon sand and zirconium oxide prices persistently hovered at lows, trading was sluggish, and the market was at the bottom of the cycle. Since entering Q2 this year, driven by export controls on zirconium products to Japan, price hikes by overseas zirconium ore producers, and demand expectations for solid-state batteries, zirconium raw material prices stopped falling and stabilized, inventories destocked, and the industry moved out of the bottom range, embarking on a volatile recovery trend. Upstream zircon sand imports have tightened, overseas miners continue to raise prices, and cost support has been strengthening. Dongfang Zirconium Industry completed a round of price hikes in April and raised zirconium product prices again on June 18. For the zirconium market outlook, supported by tightening raw material supply, zirconium prices will hold up well in the short term. Going forward, attention should be paid to changes in raw material supply and downstream demand. Rare Earth In the rare earth market: Rare earth oxide prices were relatively stable overall, but downstream purchasing activity has decreased as the holiday approaches. Pr-Nd oxide and dysprosium oxide ended their three-day winning streak and both pulled back slightly on June 18, while terbium oxide prices held steady on June 18 after a previous three-day rise. Expectations for production cuts in the scrap recycling sector and news-driven factors previously drove Pr-Nd prices, dysprosium oxide, and terbium oxide higher. However, after the afternoon session on June 17, shipments of Pr-Nd oxide from traders increased slightly, and the center of the actual trading range shifted lower. For medium-heavy rare earths, oxide suppliers held firm offer prices, but actual buying from metal enterprises was limited, and downstream magnetic material enterprises showed limited acceptance of high metal prices. Affected by the stalemate in market trading, rare earth prices are expected to move sideways in the short term. Tin Additionally, in the tin market: On June 18, the average price of SMM 1# tin fell 0.93% from the previous trading day. Driven by the US Fed keeping rates unchanged but signaling a hawkish bias, with half of policymakers expecting rate hikes this year, nonferrous metals fell overall and tin prices also pulled back. Currently, on the fundamental side: (1) Supply side: In June, most smelters focused on maintaining stable production. (2) Demand side: Downstream purchases were cautious, buying according to orders. Spot market: Overall trading sentiment in the spot market was light. Although tin prices have pulled back, they remain at relatively high levels and the holiday is approaching. Additionally, as the electronics industry enters its traditional off-season, downstream enterprises such as solder makers are only purchasing on a "buy on dips for essential needs" basis. Institutional Views Guojin Securities’ research report on June 14 showed: Rare Earth: Dysprosium oxide may benefit from the boost by MLCC, with a significant rebound trend from price lows. From the start of the year, the price center has continued to rise. We believe this is likely related to supply-side documents released in 2024-2025, with ongoing supply-side reform in the industry. Exports fell 1% YoY for full-year 2025, while exports from early 2026 to date have increased significantly, indicating strong restocking demand outside China. The rare earth sector will continue to see dual improvements in valuation and performance, and 2026 is also a key year for resolving industry competition among key targets. On the resource side, attention is recommended for China Rare Earth (medium-heavy rare earth leader, biggest beneficiary of supply-side reform), Zhongxi Nonferrous (undervalued, high-growth South China rare earth leader), and China Northern Rare Earth (light rare earth leader, with significant cost advantages); other related targets include Bao Gang United Steel, JL MAG Rare-Earth, etc. Tin: It believes that invisible inventory of tin ingots is gradually drying up, so tin prices are expected to strengthen under the backfill of macro liquidity or spillover from tech markets. The supply-demand pattern for tin will improve in the long term. Tungsten: This period, tungsten prices continued their rebound trend. It believes that against the backdrop of increased strategic stockpiling outside China, tungsten may have higher priority; tungsten's supply-demand fundamentals have seen strong resonance. Molybdenum: The destocking of imported ore has been significant, and domestic molybdenum prices have stabilized and rebounded. Steel procurement volume remains robust, destocking along the industry chain is progressing, and the deadlock of molybdenum prices with "volume but no price" is gradually being broken, with the upward channel becoming clearer. Molybdenum is also a military metal, with persistently low inventory, and increased defense spending outside China may further boost molybdenum prices. Huafu Securities’ research report on June 14 showed: Other Minor Metals: Industry leaders' long-term contract performance was impressive, and market sentiment in tungsten clearly stabilized. The tungsten market overall has walked out of a mild recovery, with the previous consolidation at lows being reversed somewhat. Industry leaders' long-term contract transactions were impressive, serving as a key driver for the upward movement in futures, and overall market sentiment clearly stabilized. However, the spot and scattered cargo atmosphere remained mediocre, with no widespread price-following adjustments upstream or downstream, and the rebound pace was gentle, with the market overall in a stage of steady recovery. Open Source Securities' 2026 mid-year investment strategy for the metals industry showed: Copper: Supply side, most miners outside China still face declining grades and recovery rates, and disruptive factors persist (Ivanhoe’s KK copper mine, Codelco’s El Teniente copper mine). While Chinese enterprises are increasing output, the overall increase is limited. Under an optimistic scenario, global supply growth may be below 2% in 2026-2027. Demand side, H1 electricity demand in China and the US maintained high growth rates, which may contribute marginal increments to copper demand. Open Source Securities believes that the supply-demand structure contradiction for copper will further highlight in 2026, supporting the rise in copper price center. Lithium: On the supply side of the lithium industry, capital spending cuts and the gradual formation of supply discipline, coupled with frequent disruptions, have led to a marked decline in supply elasticity compared with the past. Meanwhile, sustained strong demand from the energy storage sector is improving the structure of lithium demand, while industry inventory pressure is easing marginally. Lithium prices are expected to see a phased recovery. Enterprises with advantages in resource security, low costs and integrated layout are likely to show stronger earnings recovery than the industry average. Lithium mines and lithium chemicals companies with high resource self-sufficiency and strong cost control deserve attention. Tungsten: As an advantaged strategic metal in China, tungsten mine supply is constrained by resource depletion, environmental protection and other factors. Together with the total mining volume control implemented by the state, tungsten mine production release is limited. On the demand side, emerging sectors are boosting tungsten demand, which is expected to support tungsten prices over the long term. Recommended reading:

Overseas hafnium prices skyrocketed from $5,000 to $13,114.75/kg by April 2026, squeezed by AI-driven semiconductor demand and China's export controls, with high prices likely to persist.
